| Abstract: | Controller of hybrid power system is designed to realize dynamic coordinated control. Controller is composed of power pretreatment module, throttle control module and the work pattern recognition mod- ule. Controller input parameters are hydraulic pump torque,hydraulic pump rotate speed and battery SOC. Controller output parameters are diesel engine throttle angle. Simulation model of controller performance based on MATLAB is established. Performance simulation under mining condition and formation condition is developed. Simulation results show that controller can adjust motor working status real time according to load change. Diesel engine rotate speed is almost constant during the working process. |
